V EN TILA'I'OR.

To all whom z't may concern: v Be it known that I, Hnrinr A. S HMEL a citizen of the United States, residing; at

Perhain, iirtlie county of Ottertail and State of Minnesota, have invented certain new and. useful Improvements in Ventilators, of which the following is a specification.

My invention relates to ventilators, and

has for its object to provide a device which,

when subjectedto a current of air, as the .windor the currents caused by the move- "ment of vehicles, such as a street-car or train, will operate either to force fresh air into the compartment or building to which the ventilator-is attached or to withdraw the foul air from said building. It is the object of'my invention to provide a' device of this character having a trumpetlike extension and means for positioning said extension so that the same is turned toward the direction of the current, together with controllable means whereby the current of air which is forced into the apparatus through said trumpet may "either be caused to enterthe building directly or to pass through the apparatus-and thereby withdraw air from the interior of the building.

- an open-mouthed funnel 19.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims. i

In the drawings, illustrating the application of my invention in one form,-Figure 1 is a sectional elevation showing the apparatus in operative position. -Fig. '2 is an illustration showing a pair of the devices mounted, as, for example,.ona car, one.op--

crating to force air into the car and the other to withdraw air from the car. Fig. 3

of a building or car and a tubular extension 12 through said wall which may be con-- necteddirectly with a funnel 13 at the inside of the building or may be extended as indicated in dotted lines at 1 1 to any desired point.

Upon the end of tubular standard 10 and surrounding the open end thereof, I secure a bearing ring 15. I

Resting upon ball bearings 16 in a groove in the bearing ring 15 is a ring 17 which supports a tubular bodymember 18 having The tubular Specification of Letters Patent. V

member 18 is often also open at its other end 20. It will be seen that this member is mounted to swmg'about a vertical axis on the ball bearings '16.." It is held position by keepers 21 secured thereto and overlaps the ring 15.- A vane 23'sec ured to the tubu- I lar member 18, preferably by means of wires i within the'passageway 25 in member 18 and tend to flow through the same.

A closure. 26-ispivoted at 27 in member- 18 and normally. held in position to "close the passageway 25 by means of 'aweight tubular standard 10 which communicates with extension 12 or 14:. When therefore con'11: ressed"within the passagewa 251 caused to flow downwardly through member Thefpassageway opens directly, as indlcated at 26', into passageway 27 within "the closure26 is normal operative posi- 7 171011, as ind cated at Fig. 1," the air which is 12 to be delivered withinthe room or car.

through the' air ata considerable rate of speed, as upon the roof of a car, the comlVhen a windofany strength is blowing, or when the apparatus is caused to move pression of the current by funnel 19 will generate a .suiiicient draft/to force thefair rapidly and a long distance through eXtension 12 or 14.

A projecting lip' 28 is provided which extends upwardly into passageway 25 in front of the opening 26 into passageway 27.

Then it is desired to ventilate by withdrawing the air by suction the closure 26 is drawn down into the position indicated in dotted lines by means of cord 29. Passageway 25 is thereby opened so that the current of air compressed therein will move treelythrough the-same and discharge through opening 20. The movement of this current of air over the mouth 26 extending into passageway 27 will have the effect of dragging a certain amount of the air with which this current comes in frictional contact at the opening 26 through passageway 27 and from the interior of the room or car, air from the interior.

This ventilating apparatus is particularly desirable for sleeping cars, where, as indicated in Fig.2, one member may be used for member for introducing fresh air directly This will operate to draw the drawing the air out of the car and the other into the car. The ventilating devices may be made small so that an independent air introducing device may be applied to each berth of the car and larger withdrawing devices be used for the entire body of air in the car. Each passenger in each individual berth will therefore be supplied with pure air which may of course be introduced and spread in such manner as to avoid drafts.

The further great advantage of this ventilating device for dwellings will be apparent. The devices can be placed on the highest portions of the dwelling and the extensions 12 or 14 run into the sleeping chambers and fresh air be introduced and foul air removed by the action of the wind, thus preventing the necessity of opening up the storm windows during cold and especially windy weather.

The device can be constructed very cheaply, and easily applied to any building or car Without modifying the construction thereof in any particular.

I claim:

1. A ventilating device comprising a hollow vertical standard secured to the roof of a building or car, said standard providing a single passageway extending through said roof, a conductor connecting said passageway with any part of the interior, an openmouthed tubular member rotatably mounted upon said standard having the interior thereof in full communication with said passageway and having a funnel-shaped mouth, a vane for causing said funnel mouth to face the Wind, and means within the tubular member controllable within the building or car to cause the current of air compressed in said funnel to deliver fresh air through said passageway into the building or car or to Withdraw foul air through said same passageway from the building or car.

2. A ventilating device comprising a hollow vertical standard secured to the roof of a building or car, said standard providing a single passageway extending through said roof, a conductor connecting said passageway with any part of the interior, a tubular member of square cross section rotatably mounted upon said standard having the interior thereof in full communication with said passageway and having a funnelshaped mouth and a discharge opening, a vane for causing said mouth to face the wind, a damper hinged to the bottom of said tubular member near the open discharge end, a weight attached to said damper to hold said damper in an oblique position normally mouthed. tubular member rotatably mounted upon said standard having the interior thereof in full communication with said passageway and having a funnel-shaped mouth, a Vane for causing said funnel mouth to face the Wind, and a lip on said funnelshaped mouth ad acent-the opening to said passageway for deflecting the air current upward to cause a vacuum and produce suction in said passageway.

In testimony whereof I atfix my signature in presence of two witnesses.
